Pre-processed source file

I'm getting an ICE compiling a Fortran file. I'll attach a stripped down
reproducer that demonstrates the problem (the real file is 3000+ lines and
requires many, many external modules and libraries).

Per instructions, running gfortran on our .F90:

$ gfortran -v -save-temps MAPL_LocStreamGet.F90
Driving: gfortran -v -save-temps MAPL_LocStreamGet.F90 -l gfortran -l m

Log:
Refactor implicit function template implementation and fix 58534, 58536, 58548,
58549 and 58637.

gcc/
    * tree.c (grow_tree_vec_stat): New function ...
    * tree.h (grow_tree_vec_stat) (grow_tree_vec): ... and its declaration
    and macro front-end.

    * parser.h (struct cp_parser): New members implicit_template_parms,
    implicit_template_scope and auto_is_implicit_function_template_parm_p.
    * parser.c (add_implicit_template_parms): Refactor as ...
    (synthesize_implicit_template_parm): ... this to append a new template
    type parm to the current template parameter list (introducing a new list
    if necessary).  Removed push_deferring_access_checks.
    (finish_fully_implicit_template): Removed pop_deferring_access_checks.
    (cp_parser_new): Initialize new cp_parser members.
    (cp_parser_parameter_declaration_clause): Consider auto as implicit
    template parm when parsing a parameter declaration (unless parsing an
    explicit specialization).
    (cp_parser_parameter_declaration_list): Remove local
    implicit_template_parms counter and reset cp_parser implicit template
    state when complete.
    (cp_parser_lambda_expression): Reset implicit template cp_parser members
    whilst generating lambda class.
    (cp_parser_function_definition_after_declarator): Reset implicit
    template cp_parser members whilst parsing function definition.
    (make_generic_type_name): Respell '<autoN>' as 'auto:N' which works
    better with template diagnostics.
    (cp_parser_simple_type_specifier): Synthesize implicit template parm on
    parsing 'auto' if auto_is_implicit_function_template_parm_p and provide
    diagnostics ...
    * decl.c (grokdeclarator): ... that were previously done here.
